Abstract

Lithium ion battery is generally used in the Electric Vehicles and it becomes necessary to build an efficient model and simulate it so as to obtain the characteristics of the battery. To build a battery model, first a cell model has to be built, upon which the entire battery model can be formed. The goal of this paper is to build an Lithium ion cell (LiFePO4) model from the available data and to simplify it, thereby obtaining a simpler model upon which the entire battery model and the charging system can be designed. The current in amperes, current direction and the capacity of the cell is required to calculate the state of charge (SoC).
